Nanowire growth for sensor arrays

A nanowire-based sensor array for in-situ gas and biochemical sensing including spacecraft safety monitoring, gas emission monitoring, air and water quality monitoring, and fire detection are designed. To prove our concept, we have fabricated bundled metal (e & Pd, Au), metal oxide (e.g. / Sb203. 110A and conducting polymer (polyaniline) nanowires IO detect Hz. glutamate, and thyroid hormone using a cost-effective, and high-yield electrodeposition method. Our final form of nanowire-based sensor array will reduce power consumption at least by a factor of 10 by replacing the 100 nW bundled nanowire sensor array with a single nanowire pixel for each sensing material design. Innovative concepts employed in this work include the fabrication of a nanowire array with individually addressable sensors that allow single nanowires to sense gases and biomolecules
